U.S. Nuclear Submarine Makes Historic Iceland Port Visit Strengthening Arctic Security

The Los Angeles-class nuclear-powered attack submarine USS Newport News made a historic port visit to Iceland's Grundartangi harbor on July 9, 2025, marking the first time such a vessel docked on Icelandic shores. This visit underscores the United States' and NATO's commitment to Arctic security and collective defense amid increasing Russian and Chinese military activities in the region. The USS Newport News, a 36-year-old submarine with multiple Arctic Service Ribbons, plays a critical role in multi-mission operations including anti-submarine warfare, intelligence gathering, and power projection. Iceland's decision to allow nuclear-powered but non-nuclear-armed submarines to use its ports strengthens allied surveillance and protection of critical underwater infrastructure while ensuring the country remains free of nuclear weapons. The visit reflects deep coordination between the U.S. and Iceland, highlighting the strategic importance of the Arctic as new maritime routes open due to melting sea ice. Enhanced NATO patrols and surveillance efforts in the High North accompany this milestone, demonstrating a robust response to evolving global security challenges.
